Hon, ou inns momias, IOWA IN iii-DISTRIBUTOR-ROLLER STRUCTURE Application' lei August 19, 1929. Serial No. 386,936Q

The object of my present invention is to provide an ink distributor roller structure of improved design, the details of the present device being a substantial improvement over the ink distributor illustrated in my Patent No. 1,698,123, issued January '8, y1929. Y

A further object is to provide meansfor supporting and actuating an ink distributor roller, suchmeans'being of simple durable and comparatively inexpensive construction.

More particularly, it is my object to provide bearing structuresvfor an ink distributor roller including Va novel means of adjustment for adjusting the bearing structures relative Vtotheir respective supporting devices.

Another object is to provide improved means for actuating a swinging bearing from an oscillatable shaft.

With these and other objects in view my invention consists -in the. construction, arrangementfand combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter vmore fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which: y.

Figure 1 is a plan view of a printing press lillustrating my improved type of ink distributor'roller associated therewith. l

' Figure 2 is anvenlarged sectional viewv on the line 2-2 of Figure 1, showing'the ink distributor roller in one position.

Figure 3 is a similar view, showing the ink distributor roller in another position.y

Figure 4 is an'enlarged sectional view on the line 44 of Figure 'gand VFigures 5,6,7 and 8 are detail sectionaly views on the lines 5 5, 6 6, 7-7 and 8 8 respectively of Figure 4.'v

VOn the accompanying drawings, I have used the reference numerals 1 0 and 12 to in-` dicate the side frames of a printing press. rIfhe printing press herewith illustrated is the typein which a transverse ink roller 14 distributor. rollers'1`6 are and. a pluralityofV angularly disposed` ink journaled on the side frames'lO and 12. l

TheV ink roller 14 is actuated for rotation by means notherein disclosed.

1 My: ink distributor roller structure conthe slots and into the framemember 10 sists of a roller A having one end universally and slidably mounted1 in a bearing structure B. and itsother end universally mounted in a bearing structure C, which is movable. The roller A'is freeto rotate. i

The stationary bearing structure B is adapted for mounting on theside frame l0 of the printing press andthe movable bearing structure Cris secured to a rock shaft 18 carried by a bracket 20'secured to the side frame 12` of the printingpress.

The bearing structures B and C each 'consistof av bearing member 22 of a sleeve-like` construction having a hemispherical socket in its upper end. A -cap 24 is provided for each bearing member 22 'and has asimilar hemispherical socket. j'

vThe sockets just referred to are adapted to receive ball members 26 and 28. The ball member 26 is provided-with a borev through which'one end of a roller shaft 30 is slidably and rotatably mounted.` The ball 28 is formed on or secured to the other end of the shaft 30. The ball 28 and the ball 26 each sleeve member v32 and a studv 38 screw 22 is received in such groove forallowing rotation of the sleeve member' 32 relative to the bearing member 22, but preventing longitudinal movement of one relative tothe other. `Another annular groove 40 is cut in the outer surface of each sleeve memberV 32 with ywhich aset screw 42-may coact withouty damaging the outer surface ofv the sleeve member 32 when the set screw is tightened. Each sleeve'32 is internally screw threaded and one sleeve coactswith a supporting rod 44, which is likewise screw threaded, whileV the other coactsv with av supportingfrod 46. The supporting rod 44 is formedon az'foot 48 having slots 50. Bolts 52 extend through of the printing press;

threaded or driven into the bearing member Y ioY rEhe supporting rod 46 terminates in a split head 54 adapted to be clamped by a screw 56 to the outer end of the rock shaft 18.

The bracket 20, in which the rock shaft 18 is journaled, has an elongated sleeve 58, one end of which extends through-an opening 60 in the frame member 12, whereby a long bearing is provided for the rock shaft 18.

As best shown in Figure 8, the bracket 2O is provided with a hole 62 through which a bolt 64 extends for bolting the bracket 2O against the side of the frame member 12.` Ihe frame member 12 is usually provided with ribs 66 with which flanges 68 of the bracket 2O may coact for holding the bracket in alignment.

The inner end of the rocl shaft 18 is provided with a head 7 0 having a slot 'Z 2 therein. A block 74 is adapted to slide longitudinally in the slot 7 2. The block 74 is pivoted on a pin 7 6 having `a square portion 'Z 8. v'Ihe square portion 78 extends through a slot 8O formed in an arm 82.

A clamping nut 84 is associated with the outer end of the pin 7 6 (which is screw threaded) for clamping the shoulder formed by the round portion of the pin 7 6 which is mounted in the block 7 4 against one side of the arm 82.

The arm82 has its lower end seated against a rock shaft 86 mounted on the printing press and a cap 88 is associated therewith. rll`he cap 88 is securely clamped to the arm 82 by means of bolts or screws 90 and a set screw 92 prevents turning of the arm 82 relative to the shaft 86. rEhe shaft 86 is part of the printing press and is ordinarily driven by aV reciprocable linlr 94 connected with an arm 96. The arm 96 is secured to the shaft 86. Each end of the shaft86 is provided with an ink roller arm 98 adapted to support an ink Violler 100.

In the operation of the device, the inl; roller 100 is adapted to assume the position shown in Figure 2 for collecting ink from the ink roller v14. The roller 100 then swings upwardly, as shown in Figure 8, so that a printingbedl 102 traveling thereunder will collect ink therefrom.

The angularly arranged rollers 16 serve in Y a measure to distribute the ink on thefprinting bed 102 as the printing bed travels in a left hand direction under the rollers 16, but in actual practice does not evenly distribute it.

It has therefore been myV object to provide the ink ldistributor roller A having one end universally mounted in a stationary bearing `and its other end mounted in a movable bear-` ing so that the roller A, by moving to an angular position, can contact'with one of the rollers 16, as shown in Figure 1 or can be moved to a directly transverse position for Vcontacting with the roller 100, as shown in Vdotted linesr in Figure 1.

The operation and advantages of this roller are fully set forth in my former patent.

The present invention has to do with the improvements in design, whereby the device is easily adjusted to different printing presses and may be accurately adjusted for proper operation after being installed.

For instance, the height of the bearings B and C may be easily adjusted by loosening the set screws 42 and turning the sleeve members 82 in the desired direction and the desired aniountfor raising or loweringthebearings.

The foot 48 of the stationary bearing B may be adjusted relative to the frame 10 because of the slot connection 50. The movable bearing C may be adjusted circumferentially with respect to the rock shaft 18 v'by loosening the clamping bolt 56.

The amount of throw imparted tothe supporting rod 46 may be varied by adjusting the pivot pin 76 longitudinally relative tothe slot 80 in the arm 82 vand the arm 82'itself may be adjusted around the oscillatable shaft 86l as desired. j

'I'he clampingsnut 84V and the pin 76 may be loosened so that the block 74 can beshifted up or down to lengthen or; shorten the throw of the roller A. Itfwill be obvious'that thus shifting the blocl74 changes both the operating-'radius ofthe arm 82`and the head 7.0. These adjustments can be made without disassembling'any of the-parts of thedevice, as was found necessary in the construction illustrated in my former patent.

Some Ychanges may be made in the construction and arrangee'ment of the parts `of Amy device without-departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims', any modified forms-of structure or use of mechanical equivalents, *which vmay be reasonably included within their scope.
